Abstract (en)
[origin: EP3866248A1] The application provides a cell, including an electrode assembly, a package, a bonding layer and an electrolyte solution, wherein the electrolyte solution is packaged in the package and is bonded to the package via the bonding layer. A total weight m (g) of the electrode assembly, the package and the electrolyte solution, a minimum encapsulation strength F (N) between a tab of the electrode assembly and the package, a maximum bonding force f (N) of the bonding layer, a maximum distance x (mm) of the bonding layer in a width direction of the electrode assembly, and a maximum distance y (mm) of the bonding layer in a length direction of the electrode assembly satisfy the following relationship: 0.098m/a≤f<F, where a is a smaller value in x and y, causing less risk of electrode assembly tearing or the breaking of the package through the electrode assembly in case of dropping.
